Module Properties: Non-isolated step-down module (Boost)
Rectification: Non-synchronous
Input Voltage: DC1.25V ~ 30V
Output Voltage: DC3.0V ~ 35V (adjustable/fixed)
Rated Current: 2A
Output Current Max: 3A (suggest add heat sink if output power over 15W)
Once the output is fixed, its depend from the input voltage.
